What is the fee of stole in Fe2O3?Determine the charge on a multi-charge ionTotal ion charge1.2.3.4.+6+3Fe2-6-2O3Determine the charge on the various other atomMultiply the charge by the subscript ie. 2 x 3 = 6This is the complete charge for the various other ion.Divide this number through the subscript and that is thecharge on each of the ion.Charge the eachionH –hydrogenN – nitrogenO – oxygenF – fluorineCl – chlorineBr – bromineI – iodineAt- astatineAll composed asdiatomicmolecules inelementalstateCreation the oxidation numbers1. If the atom has less 보다 3 electrons thenthe atom will offer them up.2. If the atom has an ext than 5 electrons thenthe atom will get up come a complete of 8electrons3. If the atom has 4 it have the right to go either way.4. The transition metals are exceptions tothese rules and they can follow them or not.1- mono2- di3- tri4- tetra5- penta6- hexa7- hepta8- oct9- nano10 - decaIf the polyatomic ion ends in ate,replace through -ic + acidIf the polyatomic ion ends in ite,replace v –ous + acidIf the acid is binary – begin with hydro,then use the anion & end with – icif surname ends in ic,then look because that a polyatomic ion finishing in ateif the name has actually the prefix hydro- the is a binary acidanion is more than likely a halogen.HCO3-1 -bicarbonateSO4 –2–sulfate-2SO3-sulfite–2CO3- carbonate-1ClO4-perchlorate-1ClO3-chlorate-1ClO2-chlorite–1ClO–hypochlorate–1OH– hydroxide–1NO3– nitrate-1NO2- nitrite-1CNcyanidePO4 –3– phosphate+1NH4- ammonium-2S2O3-thiosulfate–1C2H3O2 – acetateMnO4-permanganate-2CrO4-chromateCr2O7-dichromateYesIs it ionicDoes the cation have much more than1 oxidation number?YesNo1) identify charge on cation2) write full name complied with bya roman numeral3) write anion name ifpolyatomic – if just 2atoms, then surname ends inide1. Write complete name ofcation.2. Write complete name ofanion if polyatomic3. Usage an concept ending ifonly two atoms present.YesIs that ionicNo1. Transform subscriptafter first element to aGreek prefix & affix tofull surname of an initial element2. If only two elementspresent use #1 come thesecond element and endname in ide.NoDoes the cation have actually a roman numeral?YesNo1. Use the roman numeralas the charge on thecation2. Balance the formula3. Use an principle ending ifonly 2 elementspresent.1. Create cation price first,anion prize second.2. Use the most commoncharge to balance theformula3. Subscripts should bewritten in shortest wholenumber ratio.1. Usage prefix together asubscript because that eachelement.2. If only2 elementspresent end 2nd inide.3. An initial element namewill not have actually a prefixif only 1 atompresent.1.2.3.4.Write out stormy formulas v reactants and also products.Balance formulas using the flow charts. Usage subscripts come balance formulasWrite the aspects on both political parties (you might delete this action later).Starting through the left side use coefficients to acquire equal variety of the same elementon both sides of the equation. Usage coefficients come balance equations.5. Leave H & O until the end.6. If you acquire an odd-even coefficient result, go earlier an dual all coefficients assignedto that point.Total massive ingrams = 1 moleParticles6.02 x1023 particles = 1 moleMoles the 1stsubstanceGramsLitersRatio ofcoefficientsParticlesMoles the 2ndsubstance
